Letters Patent No. 109,950, dated December 6, 1870.

IMPROVEMENT IN EL EVATORS AND DISTRIBUTERS.

The Schedule referred to in these Letters Patent and making part of the same.

' `and county of Baltimore, in .the State of Maryland,

have made certain new and useful Improvements in Machine for Elevating and Conveying Building Materia-ls; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing forming part ot' this specification.

Figure l is a side view; and

Figure 2 is ,a top view ofthe upper platform.

Similar letters of reference in the drawing indicate corresponding parts.

The object ot' this invention is to provide for publie use a machine adapted to elevate or convey bricks, mortar, and other building materials from the ground to the place where they are to be used in the building by means ofthe power of one man applied at the surface ofthe ground.'

.lhis result 1 accomplish by the use of a machine especially constructed and adapted to this particular pui-pose, as hereinafter described, the essential parts of which are, first, an elevated projecting platform, designed, when in use, to rest at one end upon `the wall ot' the unfinished building;vsecondly, a post or column supporting the platform at or near the outer end; thirdly, a suitable pedestal or `base for the eolumn, sufficiently extended transversely to the platform to prevent `lateral swaying or insecurity of the latter; fourthly, elevating and conducting-belts, pro- `videdwith-'hods or buckets for the materials to be raised; and, lastly, a suitable apparatus for enabling one man, standing at the baseot' the column, to pnt saidbelts in operationby hand or other power a i'.lhe invention consists, not in the use of any of these elements alone, but in the wholemachine, constructed so as to combine and adapt them to the spe# cial purpose referred to.

s represents the elevated platform, supported cccentrically upon a column, t, soV as to adapt the longer or projecting end of the platform to extend to and rest upon the unfinished wall of the built-lino.

. o is a base or lower plat-forni, resting on the ground at right 4angles with the upper platform, and supportng the column t.

e is an endless vertical apron or belt, provided with hods or buckets, h h, and extending from a point near the groundto a point over the upper platform..

on -is an endless horizontal apron operating upon the upper platform, and adapted to'reoeive the bricks and mortar dumped upon it from the vertical apron, con-v vey them along and deliver them trom its projecting end tothe place vwhere they are wanted for use on the building.

o a, b b, .and lr r are the rollers and standards that support and opel-ate the Vertical apron;

p 1),;2 z are the standards; and

q q', the rollers thatv support and operate the horizontal apron; and

lu e' 'lc le l are the gear-wheels by which the movement of the vertical apron is communicated to the horizont-al one.

The whole are so constructed, arranged, and oom-l bined that a workman standing at the basev of post t operates the vertical apron by means of a hand-crank or horse-power, and the motion of said apron communicated through the gear-wheels described is imparted to the horizontal apron, so that the materials placed in the hods by the Workman below are delivered to his companions on the building as fast as wanted.-

I am aware that a combination of vertical and hori-l zontal aprons for the purpose of elevating, conveying, and discharging dirt has been used on excavators and similar machines. I do not claim the combination of said aprons; but

What I do claim as my invention, and desire to secure. by Letters Patent, is-

The machine herein described,"consisting essen tially of the base o, the column t, the platform s, arranged at right angles with the lower platform 0 and projecting at one end so as to rest upon the wall of the building, the revolving aprons 'm e, the connecting-gear u -w It Z, and the operating wheel or drum a at the foot ofthe vertical apron', all constructed and adapted to operate together, for the purposes specij tied, in the -mannfn' substantially as herein described.

- THOMAS Sl-IANKS.
